Question

what is volume flow rate

Answer 1

In physics and engineering, in particular fluid dynamics and hydrometry, the volumetric flow rate (also known as volume flow rate, rate of fluid flow or volume velocity) is the volume of fluid which passes per unit time; usually represented by the symbol Q(sometimes V̇). The SI unit is m3/s (cubic metres per second). Another unit used is sccm (standard cubic centimeters per minute).
